Abstract: A spinal cage implant is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthoesis. The implant comprises a central part with walls and terminal parts for bearing against the cortical bone of the vertebral end plates. The implant bears against the vertebral end plates with terminal parts and contains bone graft material between walls with an opening to permit bone fusion between the two vertebrae. The implant permits restoring the physiological lordosis and the intervertebral height.

Abstract: Tools and methods for spinal fusion are provided. The tool is configured to cut openings into first and second vertebrae to receive a spinal implant between the vertebrae. The tool includes a proximal handle connected to an elongate shaft that extends to a distal end. The distal end includes a first non-cutting portion through which the shaft extends, a cutting portion fixed to the shaft to rotate with rotation of the shaft, and a second non-cutting portion fixed to the cutting portion.

Abstract: A spinal cage implant (1) is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthrodesis. Implant (1) comprises a central part (3c) with walls (4) and terminal parts (5, 6) for bearing against the cortical bone (14) of the vertebral end plates (15, 16). Central part (3c) is adapted to penetrate the vertebral end plates (15, 16) and transversely projects from the terminal bearing parts (5, 6). Implant (1) bears against the vertebral end plates (15, 16) with terminal parts (5, 6) and contains bone graft material between walls (4) which penetrate the openings (19, 21) in the end plates (15, 16) and permit bone fusion between the two vertebrae (V1, V2). Implant (1) permits restoring the physiological lordosis and the intervertebral height.

Abstract: This instrumentation comprises valves (2) for shifting aside tissues and vessels, pins for fixing each valve (2) to the spine, each valve (2) comprising for this purpose sleeves (6) in which the pin (5) is slidable; the instrumentation further comprises, for each valve (2), an articulated device (7) comprising a clamp (12) for clamping a rod (13) fixed to the valve (2); the clamp (12) may be articulated to a ball and oriented in all directions in space while the rod (13) and the valve (2) are adjustable in translation in the clamp (12); the articulated devices (7) are adjustably slidably mounted on a support frame (8). The instrumentation further comprises a push member which is capable of bearing against the valves (2) and preventing them from slipping on the surface of the spine while they are being placed in position. This device permits conveniently orienting the valves (2) in all directions and in translation.
